Hello Harry,
In this situation the device might get damaged. The TMUX6236 is not capable to operate beyond the supply. If the power rail voltage drops below the input voltage, the device will not be able to tolerate it and might won't work.
What is…
Part Number: TMUX6236 Other Parts Discussed in Thread: TMUX7236 This post is made to warn designers wanting to use the TMUX6236 as there is an error in the datasheet. The datasheet was downloaded though the TI website via this link: https://www.ti.com…
Hi Clemens,
Thank you for your support.
Does this happen if the ground levels are different? When testing with the power supply, the ground level was the same. I think it's a problem because it's currently in the board(TMUX6236)-to-board(MCU) test.…
Hello Nishie,
1.Yes the graph means that a signal of less than 10Vpp can be input when frequency=1 kHz and yes there is a limit on the frequency when passing a +/-12V signal through the mux ( I can look into this further if that is needed)
2.The TMUX6236…
Part Number: TMUX2889 Other Parts Discussed in Thread: TMUX4827 , TMUX6236 Can "TMUX2889" swith the input signal of 125kHz/10Vpp sinusoidal wave?
There are below description in the data sheet. - Signal path input/output voltage is -5.5V min and…
Hi Kameron-san,
It seems difficult to change to TMUX6236 because the customer's circuit already has a single power supply of 5V.
Is TMUX2889 also unusable under the following conditions like TMUX4827?
Vdd=5V single power supply Input signal: +/-5V…
There is no transceiver that allows selecting LVTTL voltages.
Anything involving RS-232 voltages needs extended power supplies. It might be possible to combine an RS-232 transceiver with three drivers like the TRS3386E/MAX3386E and a > 10 V switch like…
There are clamping diodes at the I/O pins:
When you go above V CC + 0.5 V, a current flows through the diode into V CC . If the current becomes too high, the device gets damaged.
In any case, with voltages above V CC , the switch no longer works correctly…
Part Number: ADS8588H Other Parts Discussed in Thread: INA188 , TMUX6219 , OPA2197 , TMUX6236 Dear TI,
We need a programmable Gain amplifier which should have gains of 10 and 50,
input to ADC AD8588H is being fed from current transformer, and we want PGA…
